Areas affected...eastern Ohio into far western Pennsylvania

Concerning...Severe Thunderstorm Watch 80...

Valid 251807Z - 251900Z

The severe weather threat for Severe Thunderstorm Watch 80
continues.

SUMMARY...The severe threat continues across Severe Thunderstorm
Watch 080. Damaging gusts will be the main threat with the stronger
storms.

DISCUSSION...Low-topped thunderstorms have been pulsing in intensity
over the last hour or so, with at least a few near-severe gusts
observed. These storms continue to progress rapidly eastward amid
very strong low/deep-layer speed shear, as shown by regional VADs.
Furthermore, ample diurnal heating supports a well-mixed boundary
layer, depicted by 8+ C/km 0-3 km lapse rates (17Z mesoanalysis). As
such, at least isolated strong wind gusts should continue through
the afternoon hours, before storms weaken as they progress over a
cooler, stable boundary layer in central PA.
